Question 625Navigation General70% to pass
Deviation which is maximum on intercardinal compass headings may be removed by the _______________.
AI Explanation
The correct answer is C) soft iron spheres on the sides of the compass.
Soft iron spheres placed on the sides of the compass can be used to remove deviation, which is the maximum on intercardinal compass headings. This is because the soft iron spheres create a magnetic field that counters the deviation caused by the iron and steel in the ship's structure, effectively canceling out the deviation on the intercardinal headings.
The other options are incorrect because: A) a Flinders bar is used to reduce deviation on northerly and southerly headings, B) transverse magnets are used to reduce deviation on easterly and westerly headings, and D) fore-and-aft magnets are used to reduce deviation on northerly and southerly headings, but not specifically on intercardinal headings.
